Question: How do you increase the sensitivity of the LDR in the Light Sensor at 12:35? Do you use a weaker resistor or a higher voltage or what?

@estechknowledge 2 года назад

If you decrease the resistor value then the sensitivity will increase and if you increase the resistor value then the sensitivity will decrease.

@richardnoordhoff4288 2 года назад

@@estechknowledge instead of a resistor you van use a potentiometer, so you have adjustable sensetivity.

@broz36_ 2 года назад

@@richardnoordhoff4288 Or you can use a potentiometer to set a specific sensitivity, measure the resistance, and then replace it with a resistor that corresponds to that resistance.

@estechknowledge 2 года назад

Offcourse using 1K potentiometer would be a great option.

I had used NPN transistor so I had connected the negative side of the LED with transistor.

Publishing circuit diagrams of the project indicates your depth of knowledge and understanding the sincerity towards your viewers. As the circuit diagram is not a binding on you, the uploading of the video is also not a binding on you. You may choose to lie idle and do nothing.

Schematics please. Or is this a music video?

@rippalmer6296 2 года назад

I tried to make the light sensor at 12:35. It worked, but it was so insensitive that I needed to shine a flashlight directly into the LDR for it to work. I was certain I used a very weak resistor. Or maybe I soldered the components to the wrong parts?

@estechknowledge 2 года назад

Might be, the LDR you are using is not so sensitive

@rippalmer6296 2 года назад

@@estechknowledge That is interesting because the batch I ordered from Aliexpress was rated as the most sensitive... or maybe I was mistaken? I will verify.

The trouble is that the circuit was not explained. No details, advice, cautions, etc. No schematic, no theory of operation, or such. For a beginner it is crap - you learn nothing.

Im here because i looking for Infos for my wireless energy Projekt. i use: TRANSMITER Transistor: bc549c NPN, Restistor 1k on collector Emiter - 15/loop/15 coil between base and + RECIVER: 30 spin, Red-LED( 1,5 Till 3,7) ______ now i See you build it too 😀😀 I have some question? Did you use ac energy on your transmitter? .. my Homemade transmiter use 9v dc.. but i must type the cable on my +side up and down on the coil .. or it dosnt work ... So i Think with ac it works Mutch better Now I find out : the Transistor push up the energy to 30v and 500w and anywhat with 300hz.. - So the coil "sends" an bigger electric field... And the coil on the RECIVER takes the Energie to the LED. i like it !!! but its works only few cm...

@patty1991 2 года назад

Can i connect 2 realis (3-9v) between collector, + and base on the Transmitter side ? ... And 2 relais (3-9v) on the RECIVER side on the LED.. For more Performace /distance ??? ______ Or must i need 2 Transistors connect parallel or so for more hz??? Google says: l=c/f || If 100 spin = 15hz ... Okey.. my own coil has 30 spin So: 15/100 ×30 = 4,5 hz ... ... 300.000(c)/4,5hz = 66,6 meters... Whats wrong ???? For 5m distance it need 1 500 000 hz Or an 73k wireing fat coil 🙃🙂😇🤣 ... 1,5 mhz ... Can i use oszilators ..or so for faster on and off and distance ??? 😀😛🤓🤓🤓🤓🤓🤓

@madhusudangupta3661 Год назад

I believe that you know something about wireless technology. It is based on propagation of radiowaves. Communication has seen a magical development due to this technology. The last project, you have covered in this video, does not fall in the category of wireless conveyance of energy by any yardstick. This technology, you have used in this project, is transmission of energy (AC Electrity) through Induction. It is widely used in Transformers. So be educated and modify the erronious claim on wireless technology, used in the project. Best wishes.
